Management Measures for Edible Fungi in Autumn

1. Fruiting management

Early autumn Pleurotus ostreatus: The management focus at this stage should emphasize the word "water". In conventional cultivation, the bacteria bag loses water severely after fruiting, so immersion or injection should be used to replenish water in order to obtain a higher yield. For Pleurotus ostreatus sown in September, the water balance should be controlled as much as possible to further mature the hyphae and accumulate nutrients to the maximum extent, laying the foundation for fruiting in October.

Flammulina: Most Flammulina velutipes fruiting has come to an end, and about one-third of Flammulina velutipes is still fruiting. The most difficult aspect of cultivating Flammulina velutipes in cold storage is moisture management. The humidity in some enoki mushroom growing places is low, resulting in unsatisfactory yield. There are two major problems: the main location for humidity measurement is 1.5 meters high, and the temperature in the cold storage is high and low, and the ground is sprinkled with water, which makes the high-rise temperature high and the humidity low; currently The raw material is rich in cotton seed husks, large husks, short linters, low water absorption (about 30%), and poor water holding capacity, resulting in "congenital insufficient" in the bacteria bag.

Agaricus bisporus: Agaricus bisporus sown in early September, the first tide mushrooms appear in mid-to-late October. Pay attention to effective hydration to the border bed after the mushrooms emerge to facilitate the second tide mushrooms.

Fungus: Due to the large temperature difference, whether it is black fungus or hairy fungus, the growth rate slows down. At this time, do not spray too much water to extend the growth period and maximize the output

Shiitake mushrooms: High-temperature mushrooms have entered the final stage of management. As the temperature becomes lower and the temperature difference becomes larger, the quality of the mushrooms will be improved. However, it should be noted that after the last bubble bag in early October, strengthen low temperature management, and a batch of high-quality fresh mushrooms can be grown. The shed should be cleared immediately and disinfected. At the end of October, it will be ready to move the low-temperature mushroom strains into the shed.

2. Bacteria management

Regardless of the secondary or tertiary species of bacteria, it should be noted that high humidity is not good for the bacteria. Ventilation management should be strengthened, and dehumidification treatment should be carried out if conditions permit. It is necessary to strictly eliminate impurities, especially to prevent the occurrence of destructive bacteria such as Alternaria. Once found, immediately cover the contaminated bacteria bag with a plastic bag and move it outside the shed for destruction.

Shiitake mushrooms: The low-temperature type mushrooms have already developed more bacteria. At this time, you should pay close attention to the temperature changes. According to the principle of "lower, not high", adjust the germination temperature, rather prolong the germination time, and don't cause bacteria bags due to high temperature Damaged. When the mushrooms in individual areas enter the post-ripening or color-changing period, try to lower the temperature. According to the growth status of the mycelium, punch holes at the right time and increase the temperature and humidity difference to facilitate the physiological transformation of the mycelium.

Regular management of medium and low temperature oyster mushrooms is sufficient. The bacteria shed is covered with anti-insect nets, and beta-cypermethrin is sprayed every 3 days to prevent the invasion of mushrooms, mosquitoes and other pests.

Agaricus bisporus: Part of the delayed cultivation of Agaricus bisporus can be sown around mid-October. The focus of management is to prevent pests and diseases. Spray 300 times liquid every 5 days to prevent the breeding of bacteria.
